My specialty is condensed matter theory. My current interest is in optical control of electron spins in semiconductor nanostructures, for quantum information processing and spintronics. My overall interest is in many-body theory in solids, especially the density functional theory, the electron-phonon effects and the many-body contribution to optical properties in semiconductors.The current and past research topics include: (Please click on a topic to see a brief description and a selection of papers.)
